The study is to further exploring the optimal switching strategy by evaluating the pharmacodynamic responses as well as adverse events in patients with complexity of coronary artery disease managed by percutaneous coronary intervention (PCI). All participants will be divided into three groups and recieving ticagrelor 90mg plus aspirin 100mg at 12 hours after the last dose of clopidogrel; recieving ticagrelor 90mg plus aspirin 100mg at 24 hours after the last dose of clopidogrel; recieving ticagrelor 180mg plus aspirin 100mg at 24 hours after the last dose of clopidogrel.
Background: the decision-making process of patients with angiographically-intermediate coronary lesions (ICL) is clinically challenging and may benefit from adjunctive invasive techniques. Fractional-flow-reserve (FFR) represents the gold standard to evaluate ICL but optical-coherence-tomography (OCT) is a novel, promising, high resolution coronary imaging technique. Objectives: 1. Investigate the relation between OCT and FFR parameters in ICL and understand if OCT measures may predict FFR. 2. Understand if OCT parameters may predict clinical outcome of patients with ICL not underwent revascularization on the bases of negative FFR. Study design: multicentre, international, individual patient's level data pooled analysis.
Bioresorbable vascular scaffolds (BVS) are considered as a new revolution in coronary intervention due to their potential advantages for long term follow up. However, current generation BVS have also some drawbacks that restrict the use for complex lesions. Using BVS and drug eluting stents (DES) together -implanting DES for BVS inappropriate segments -may be a feasible option to avoid the disadvantages of permanent foreign body and to reduce very late adverse events. In this context, we investigated the clinical outcomes following treatment with hybrid strategy with concomitant use of BVS and DES for complex lesions. A single center retrospective cohort was performed enrolling 40 patients with complex lesions treated with hybrid approach from February 2015 up to April 2017. Lesion segments with a large plaque burden and/or severe calcification, aorto-ostial and bifurcation lesions that may be unfavorable for BVS, treated with DES. BVS and DES were implanted with minimal overlap of DES and BVS struts. The primary end-point was target lesion failure (TLF) which was a composite of cardiac death, target vessel myocardial infarction and target lesion revascularization (TLR). During follow-up, coronary angiography was performed when patients had ischemic symptoms.
For permanent coronary stents, reduction of thickness of struts have become one of the most important innovation, being related to easier manipulation, reduced risk of stent thrombosis and low rate of revascularization. Consequently the investigators performed a multicenter registry enrolling all consecutive patients treated with very thin stents for ULM or bifurcation.
The aim of this study is to evaluate the relation among cholesterol uptake capacity which measure HDL functionality, neoathrosclerosis and target-lesion revascularization.
This prospective randomized study evaluates the nephroprotective effects of exogenous nitric oxide delivered to the extracorporeal circulation circuit during cardiac surgery with cardiopulmonary bypass.
Study aim : To compare a novel strategy of lesion preparation with noncompliant balloons before implantation of BVS. Hypothesis: Predilatation with non-compliant balloons could facilitate optimal deployment of BVS. By achieving good scaffold apposition a need for post-dilatation could be significantly reduced. This is expected to result in better short- and long-term outcomes.
The objective of this study is to evaluate the long-term efficacy and safety of coronary stenting with the various types of drug-eluting stents (DES) and to determine clinical device and procedural success during commercial use of DES in the real world. The investigators will compare EES (Xience V/Promus and Xience Prime), SES (Cypher), ZES (Resolute Integrity, Endeavor Resolute, Endeavor), and BES (Biomatrix, Biomatrix Flex, and Nobori).
This prospective randomized study elucidates the effects of exogenous nitric oxide delivered to the extracorporeal circulation circuit for cardioprotection against ischemia-reperfusion injury during coronary artery bypass graft surgery with cardiopulmonary bypass.
The SYNTAX-score has been proposed as a tool for risk stratification and guiding revascularization therapy in patients with complex coronary artery disease. There are limited data on the prognostic value of the SYNTAX-score among elderly patients. Aim of this study was to investigate whether age modifies the impact of the SYNTAX-score on all-cause mortality at 2 years after percutaneous coronary intervention (PCI).
